Creating the Perfect Solder Joint

From a visual standpoint, a good solder joint should be smooth, bright, shiny, clean, and have a nice concave solder fillet. But how do you ensure that inside those joints, good intermetallic bonds are formed? Solder joints play several different roles, and they represent several different opportunities to be a problem, a partial improvement, or a complete improvement. Since all solder joints aren’t created equal, the first step is to understand what is expected or required of that joint.

The Root Causes & Solutions for Warped PC Boards

There are two primary types of causes of board warping: process related at the fab or assembly shop, and layout related issues. If it's warped before assembly, it's between fab and layout. If it's flat before assembly and warped after, it's most likely between layout and assembly. That said, sometimes a fab problem won't show up until a pass through the reflow oven at your assembly partner.

They also discussed challenges and strategies in bringing more young people to the industry.

Sensible Design: Thermal Management—The Heat is On

Thermal management materials are designed to prolong equipment life and reduce incidences of failure. They also maintain equipment performance parameters and reduce energy consumption by reducing operating temperatures, and minimising the risk of damage to surrounding components. Indirectly, they maintain brand reputation, as the reliability of the equipment will be very dependent upon the effectiveness of the thermal management technique used.

Drying Boards after Rework Cleaning—To Do or Not to Do?

In cases where water soluble fluxes are being used in the rework process, in cases where the components need to have flux residues washed off, or in cases where the board needs to be cleaned with water for subsequent conformal coating touchup, proper drying and perhaps even bake out procedures need to be performed.

What's Up in Scandinavia's EMS Industry?

Scandinavia, consisting of Denmark, Norway, Sweden, and Finland, is relatively small in regards to the overall European EMS revenues, and counts for less than 6% of the European EMS production value. Nevertheless, more than 160 companies offer EMS services, not to mention companies who only manufacture cable harnesses or just do design work, box building, and after-sales services.


Rework and Reliability: Less is More!

Circuit boards are not always perfect after reflow or wave soldering. Scrapping boards with one or two defects is expensive, so rework happens. A good concept for rework is less is more, especially less flux. Use as little rework flux as possible, as in the old Brylcreem ads, "Just a little dab'll do ya."

Does My Outsourcing Project Fit with the EMS Provider's Strategy?

Once a decision has been made to outsource your electronics manufacturing, the next step is to find a suitable partner.

Should You Entrust Your EMS Provider With Your Supply Chain?

Managing your supply chain can be time consuming and expensive and, more importantly, it can distract you away from other key activities such as sales, marketing and product design. As an OEM, however, it's unlikely that your supply chain is a 'core' activity, that is, something that adds real value to your customers. So, what are your options?

Whose Fault is That Bad Board?

Years ago, I held a position in an EMS company where projects were analysed before manufacturing. We found that even some of the best and most innovative circuits could not be manufactured. Why? Because the PCB designer, an electronic engineer, was not acquainted with the fabrication process. He had no idea about technological requirements necessary for electronic production. I know another designer who learned, finally, the importance of the thermal relief pad for heat restriction during reflow for a good soldering. His response? “Oh, was that what they were for? And to think I worked so much to remove them!”

Improving the Rework Process

An optimized SMT assembly process typically provides a yield of nearly 100%. Technology advancements—from the solder paste printing process, SPI, and parts placement, to reflow and wave soldering and AOI—have pushed the efficiency and accuracy of these steps in the SMT process such that a board assembly should be perfect at the end of the line. Still, EMS providers continually face the need to rework and repair PCBAs even after dialing in the perfect set-up.

The Past and the Future of the European EMS Industry

The EMS industry in Europe is still in a growth stage of its life cycle. This does not mean that there is enough space for everybody. Looking back over the past 10 years, we have seen tremendous changes in the number of companies, counting every separate legal entity.
